SPECIFICATIONOrming part of Letters Patent No. 705,816, dated July 29, 1902.

.Application tiled March 24,` 1902. Serial No. 99.775. (No model.)

my invention; Fig. 2, a sectional view on the line a h of Fig. 1; Fig.` 3, avertical sectional view through a portion of one side tube, showing the lower end of the sleeve thereon and a spring in the tube for locking the parts together, enlarged; Fig. 4, aside view of a portion of one of the tubes, showing the bail-ear thereon, together with one end ofthe bail connected therewith ;l Fig. 5, a side view showing the application of my invention to a coldblast lantern. l

This invention relates to an improvement in lanterns, and particularly to tubular lanterns, and is equally applicable to lanterns in which the air supplied to the burner is admitted through a central tube arranged above the globe or to the well-known type ofcoldblast lanterns; and the invention more especially relates to lanterns in which the globe is swung to one side for access to or removal of the burner. In the usual construction of this class of lanterns preparatory to swinging the globe to one side it is necessary to raise it, so that the lower end will clear the top of the burner-cone, and before the globeis raised it is necessary to lift the bell or hood, and this is usually done by independent means.

The object of this invention is to arrange a sleeve upon one of theside tubesland connect the bell or hood with its upper end and also connect `the globe-holder with the tube, so that by one operation both members may be raised and when raised theglobe may be swung to one side.

Another object of the invention isY to lock the globe-holder in its normal position and to provide means for holding it in its elevated position, and the invention consists in the details of construction and combinations 0f parts, as will be hereinafter described, and particularly recited in the claims.

The base or font 2, side tubes 3 4, and central tube 5, which connects with the side tubes at the top of the lantern, may be of usual construction, as is also the burner G, globe-rest 7, andglobe-guard 8. Upon the side tube 4 is a sleeve 9, to the lower end of whichA the globe-rest 7 is rigidly connected by a wire arm 10. To the upper end of the sleeve 9 the bell or hood 1l, which is adapted to slide vertically on the central tube 5, is connected by a wire arm 12. This arm encircles the side tube 4 and is connected with the sleeve 9 by having the upper edge of the sleeve turn over the wire, a portion of the sleevebeing cutaway to form a clearanceslot 13, the purpose of which willhereinafter appear. Also secured to' the sleeve 9 is a spring-stay 14, which encircles the top of the globe 15, so as to assist in holding it in position. Within the tube 4 is a spring-catch 16, the tongue 17 of which projects outwardly through a slot 18 in the tube 4 and the slot 19in the sleeve 9. To raise and swing the globe, the tongue 17 will be pressed inward, so that the sleeve 9 may be raised, the upward movement of which will lift the hood 11, and at the same time raise the globe 15 until its rest 7 clears the burner-cone 6. By this time the lower end of the sleeve 9, within which the'arm 10is secu red, will have passed above the upper corner of the tongue 17 and the rest to a position to clear the burner-cone, so that the globe may be swung to one side in the usual manner, the lower end of the sleeve riding upon the upper edge of the tongue 17 and the slot 13 in the upper end of the sleeve permitting it to ride over Vthe wire arm 12. The globe therefore will beheld in its lifted position as long as it is turned out ofline with the burner. When the globe is swung into line, it will fall by gravity, the weight of the globe drawing the sleeve downward, and hence bringing with it the hood 11. When in their normal positions, the slots 18 and 19 will register, so that the tongue 17, extending through them, will lock the sleeve with the tube. On the upper side of the tubes 3 4 are bail-ears 20, into which the ends of the bail 2l extend, and the upper edges of these ears are formed with notches 22, into which the bail will spring when the bail is raised to its vertical position, so that the bail or handle will be held upright when desired; but the notches are so shallow and the bail so Ilexible that the bail maybe readily turned down when desired.

In applying my invention to a cold-blast lantern, as shown in Fig. 5 of the drawings, it is necessary to raise the chimney 23 prior to lifting the globe, as the lower edge of the chimney sets over the top of the globe. I therefore connect the chimney 23 with the upper end of the sleeve 24 by an arm 25, corresponding to the arm 12, by which the hood was connected with the sleeve 9 in the construction heretofore described, and on the sleeve-24 I arrange a collar 26, to which the globe-rest 27 is connected by an arm 28. In this sleeve is a slot 29, through which the tongue 17 of the locking-spring extends. In the lower edge of the collar is a notch 30,andin the upper edge is a notch 3l,while on the sleeve 24 are pins or studs 32 83, which coact with the collar, as will hereinafter appear. To swing the lantern, the tongue 17 will be depressed to permit the sleeve 24 to be raised, the upward movement of which will lift the chimney 23 upward away from the globe 15. In the meantime the pins 32 33 will have been lifted until the pin 32 comes in contact with the upper edge of the notch 30. The continued upward movement of the sleeve will raise .the globe until the globe-rest clears the top of the burner, when the sleeve may be rotated, which will turn the collar, so as to swing the globe to one side, the globe being held on its rest by usual guards 34. The notch 3l and pin 33 might be omitted, although I' preferably employ them to give ridescribed, the sleeve will be held in its lifted position, as well as locked in its depressed position, by the tongue 17 of the locking-spring.

I am aware that sleeves have been arranged upon one of the tubes of a tubular lantern, with which sleeve the globe-holder has been connected, so as to be raised thereby, and therefore do not wish to be understood as claiming such as my invention.

Having thus fully described my invention, what Iclaim as new, and desire to secure by Letters Patent, is@

1. In a tubular lantern, the combination with the side tubes thereof, of a verticallymovable sleeve arranged upon one of said tubes, rigid connection between the sleeve and globe-rest and swivel connection between the sleeve and a portion of the lantern above the globe whereby the upward movement of the sleeve will raise the globe and a portion of the lantern above the same, so as to permit the globe to be swung to one side, substantially as described.

2. In a tubular lantern, the combination with one of the said tubes, hood and globerest thereof, of a Vvertically-movable sleeve arranged on said tube, a swivel connection between the hood and the upper end of the sleeve, and a rigid connection between the globe-rest and lower end of the sleeve, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
